Horse-power



AUGUSTUS ADAMS, OF SANINVICH, ILLINOIS.

HORSE-POWER.

Specification of Letters Patent No. 32,673, dated July 2, 1861.

To all 'whom 'it may concern:

Be it known that I, AUGUSTUS ADAMS, of Sandwich, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Horse-Powers; and I do hereby declare that the following is a full,.

clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters of reference marked thereon.

The object of this invention is to develop the power of horses to be utilized on various machines, in such a manner that there will be a minimum loss by friction, and that the driving speeds may be readily changed; and it consists in attaching the levers for the teams so that there will be only a rotary strain connmmicated to the main shaft, which may be transferred to the driving pulleys by any one` of three changes of gear ing.

In the ordinary way of securing the lever for a team it is fitted into a socket at the center, and has a fulcrum more or less remote between the horses and the shaft; and the power not only rotates the shaft, but tends to displace it by the leverage from the fulcrum. The displacement of the shaft and the machine, Ais resisted by the fastenings, and occasions a large loss of power by friction. By extending the lever beyond the shaft the leverage at one side is in unison with that at the other, the disl placement of both pointsof attachment is in a circular direction around the shaft, and a strain of torsion only is communicated to the shaft. As therefore, there need be no provision made for' any other than a rotary strain on the shaft, the machine may be built much lighter than when it is necessary to resist the twisting of the driving wheel and shaft from their proper position.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l of the drawing is a side elevation of my improved horse power arranged foil two teams, and Fig. 2 is a plan of the same.

The teams are attached to the levers a, which are secured to the driving wheel L by the sockets c and l placed on opposite sides 'lever had been attached to theY center, it

would have exerted a corresponding power to displace the shaft; but by extending the lever to the socket d on the opposite side, the leverage there is also exerted simply to turn the shaft as desired. The small levers c are for the attachment ofthe horses7 halters. T he bevel driving wheel is prevented from leaving its proper horizontal position by the blocks :r and the hook 1/ and it is geared into the bevel pinion on the shaft g, which also carries the wheel /1 that drives the two pinions z' and on the shafts Z and fm. These three shafts have appropriate bearings and journals; and are all caused to revolve together by the movement of the teams, at various speeds depending upon the size of the gearing. The shaft g may have a slow motion suitable for a corn sheller; the shaft Z will then have a more rapid motion, such as would be used for a thresher; and the shaft m would be worked still faster, as would be required for a sewing machine.

The motion from either of the shafts Z, or ml may be transmitted by fitting its square end into the socket of the shifting, pulleyshaft n, which is represented in the drawingl as connected to the shaft y. The shaft n has a pair of belt pulleys from which the power is taken to the machine it is desired to work; and it has a single bearing 0 that may be shifted when it becomes necessary to take the power from either of the faster working shafts Z and m.

I claim as my invention and desireto secure by Letters Patent:

I. The attaclnnent of each of the drivingl levers to the opposite sides of the crown of the driving wheel, in the manner described and for the purposespecified.

Q. The shifting shaft n, when used for transn'iitting the motion of either of two or more revolving shafts, substantially as, and for the purpose described.

AUGUSTUS ADAMS.
